Description
In the framework of the ICDP project PaleoVan several up to 240 m deep drillings will be carried out at Lake Van (Turkey). The project aims at studying environmental and climate variations in a sensitive semiarid region. Extensive geophysical downhole logging of these boreholes delivers a basis for answering questions in the scope of this project. Interpreting the downhole logging data permits to establish a complete lithological log, to characterize the drilled sediments petrophysically, to determine sedimentary structures and to obtain evidences about palaeoclimatic conditions during up to 500 ka. Seismic experiments in the borehole allow linking the detailed geological information with shipborne seismic sections. Thus, local results can be transformed into spatial information providing an important contribution to the understanding of the sedimentological patterns and the tectonic structure of the Lake Van Basin.
